Dear Yags06,
Let us understand the different terms and definitions here:
1. **Promotion** – A promotion indicates an upward movement in a grade and salary structure due to an increase in job scope. E.g., Technician to Senior Technician.
2. **Assured Pay** – Also known as Base Pay, it is a guaranteed pay to reward the jobholder for the expected job scope. E.g., a Technician is paid S$1200, while a Senior Technician with a larger job scope is paid S$2000. Base pay is job-scope driven.
3. **Incentive** – An incentive is variable pay linked to performance or improved performance. E.g., an increase in productivity leads to a productivity incentive payout. Incentive is not a component of Base Pay. However, the summation of Base Pay, incentive, and other performance-linked variables will derive Total Cash or CTC, which is your earning potential.
To answer your question:
x amount from Base Pay CANNOT be deducted to show increased incentive in a promotion because even though you have been promoted to do a bigger job, your guaranteed pay has just been reduced, and you have to earn it back by meeting a bigger productivity quota.
This is an unlawful practice, and you should not sign any document until all your concerns are addressed by your HR.

Autumn Jane
